IMPROVEMENT IN DEVICES FOR PACKlN G ENGINES.

Specification forming part of Letters Patent No. 222,615, dated December16,1879; application filed October 6, 1879.

To all whom it may concern:

Be it known that I, DAVID WEBBERT, of.

Kearney, in the county of Buffalo and State of Nebraska, have inventedcertain new and useful Improvements in Devices for Packing Engines; andI do hereby declare that the following is afull, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same,reference being hadto the accompanyin g drawings, and to the letters of reference markedthereon, which form a part of this specification, in which- Figure 1represents a longitudinal vertical I section of my improvement appliedto a hori- Referring to the drawings, A represents a jack having aframe, a, of any suitable material, provided at each end with asemicircular guide, a, adapted to embrace the piston-rod B of the engineto be packed. Working in suitable guides in this frame is a rack, O,having ratchet-teeth b and a pusher, c,- at its outer end. At D is alever, having its fulcrum in suitable bearings in the frame, or on a pinpassing through both frame and lever, as at d, and provided with a pawl,E, taking into ratchetteeth on the rack;

Attached to the pawl is a wire, F, by which the pawl can be lifted outof the rack when it y is desired to allow the rack to move backward.

At Gr is a pawl pivoted to the frame and actin g on the ratchet-teeth toprevent any retrograde motion of the rack while the lever is beingreversed.

Surrounding the piston is a clasp, H, hinged at c, and provided withribs f and an extension at g to fill the space between the ribs. claspshould be held together by a clamp of any suitable form, or, ifpreferred, by bolts passing through the ribs; but a clamp that I havefound very convenient for the purpose is shown in the drawings at I,made in the form of pinchers with long jaws, i, to embrace the ribsfonthe clasp. One of the arms of this clamp has a yoke, K, which takes intonotches k in the other arm, by which'the clasp is held fast in thedesired position.

To use this device the glandL is first drawn away from the stuffing-boxand the packing M wound around the piston-rod B. The clasp H is thenplaced around the packing M and clamped to compress said packing, sothat it will readily pass into the stuffing-box; The jack A is thenplaced in position on the piston-rod, with one end resting against thecrosshead N of the engine and the pusher 0 against the gland L. Bygiving the proper motion to the lever D the pawl E moves the rack O withthe pusher to the left, thereby acting 011 the gland L and forcing thepacking into the stuffing-box.

By the use of this device a piston-rod can be packed with a great savingboth of material and labor.

I do not limit myself to the precise construction shown and described,as it is evident that the form of the jack or clasp may be readilychanged without varying from the essence of my invention; nor do I wishto limit myself the stuffing-box, although the packing may have beenmade much smaller originally.

IVhat I claim as new is- 1. In a device for packing engines, the framea, provided with guides to. hold it in position on the engine, and alongitudinally-moving pusher constructed and arranged to force the This2 v 222,6Ii5

4. The combination, with a jack for packing engines, of the clasp H,provided with the ribs f f and extension g, substantially as and for thepurpose specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two Witnesses.

DAVID WEBBERT.
